Two dads drink driving with kids in car

Two fathers have been caught drunk behind the wheel with their children in the car, with police saying they're alarmed by a spike in drink-driving offences on New Year's Day.

Sixty-three drivers were caught over the blood-alcohol limit on Tuesday - 37 more than on the first day of 2012.

An unlicensed 33-year-old man was caught drink-driving at Riverstone, in Sydney's northwest, just before 6pm (AEDT), police said.

It's alleged the man, who had his five-year-old daughter with him in the car at the time, returned a breath-analysis reading of 0.090.

He has been charged with mid-range drink-driving and unlicensed driving.

In a separate incident, a 25-year-old Western Australian man was caught with his nine-year-old son in the car on the Princes Highway at Fairy Meadow, near Wollongong, about 9.30am (AEDT).

He returned a breath analysis reading of 0.093 and was charged with mid-range drink-driving, police said.

Meanwhile, a 49-year-old woman allegedly returned a breath-analysis reading more than five times the legal limit after being pulled over at Banora Point, on the state's far north coast, about midnight.

She has been charged with high-range drink-driving and her licence was confiscated.
